Company profile
researched Aug 2026Cosmon is a San Francisco-based enterprise software company that develops Nexus, an AI agent for mechanical and hardware engineering work. Nexus operates directly inside engineering software and handles CAD, computer-aided engineering (CAE) and product lifecycle management (PLM) tasks through natural language, including CAD automation, design-for-X (DfX) checking, drawing generation and review, simulation setup and troubleshooting, tolerance stack-up, reverse engineering, simulation postprocessing and PLM search.
The product is positioned as a layer above individual engineering platforms rather than a single-tool copilot, with stated support for SolidWorks, Ansys, COMSOL, Abaqus, Star-CCM+, Creo, Onshape, Fusion 360, Inventor and MATLAB. Alongside the interactive application, Cosmon offers an Agent SDK that lets teams drive the same agent from Python to batch, script and embed it in their own pipelines. Cosmon describes Nexus as grounding each action in the customer's engineering sources of truth so that decisions remain visible, traceable and reversible.
According to third-party profiles, Cosmon was established in 2025 in San Francisco and is at the Series A stage, with its platform targeted at industries with complex, high-stakes engineering requirements such as automotive, aerospace, manufacturing and energy.
Founding story
Cosmon was founded in 2025 by Rui Aguiar (Founder and CEO), an engineer and researcher who previously cofounded and served as CTO of Expedock and was named to a Forbes Under 30 list, together with Noah Weber (Co-Founder and CTO).
Business model
B2B enterprise software sold to engineering organizations. Third-party profiles describe a subscription model for Nexus with multiple pricing tiers, team or organization licenses that integrate the agent into existing workflows, and the option of custom build-outs for specific client requirements.
Subscription-based licensing of the Nexus product across pricing tiers, supplemented by custom implementation work for enterprise clients, per third-party profile data.
Traction
Cosmon states that Nexus is used by thousands of hardware engineers and publishes testimonials from mechanical, simulation and engineering-management staff. Third-party profiles report roughly 10-30 employees, Series A stage, and five open roles as of August 2026. The company reported SOC 2 compliance in a April 2026 blog post.
Latest developments
In May 2026 Cosmon announced a $31.2M Series A led by Bison Ventures and South Park Commons, with Innovation Endeavors also listed among Series A investors. The company continued publishing technical content through August 2026, expanded open roles to five positions in August 2026, and is scheduled to demonstrate its agents at IMTS 2026.

Market position
An application-layer AI company in the engineering-software segment, tracked by private-market data providers as an early-stage, Series A enterprise software business; Caplight lists Leo AI, Navier AI and P-1 AI as the closest comparable companies.
Cosmon positions Nexus against general-purpose agentic AI and single-application copilots on the basis of unified coverage across CAD, CAE and PLM rather than one tool, autonomous execution of full workflows instead of step-by-step manual prompting, project- and PLM-level context rather than single-file or single-session context, and traceable, reversible actions grounded in the customer's own engineering data. Local deployment and zero data retention are presented as differentiators for IP-sensitive engineering teams.
Technology
Nexus is built on multimodal geometry models intended to interpret CAD structure, physics and design intent, and is described as trained on cross-domain synthetic engineering problems. It connects to CAD, CAE and PLM tools including SolidWorks, Ansys, COMSOL, Abaqus, Star-CCM+, Creo, Onshape, Fusion 360, Inventor and MATLAB, and exposes a Python Agent SDK for scripted and batch use. Deployment options include running locally on customer infrastructure; the company states zero data retention, no model training on customer data, and SOC 2 certified security with a public trust center.
Go-to-market
Direct enterprise motion combining self-serve product trials and booked sales calls from the website, a technical content program (guides and insight posts on CAD, CAE and security topics), developer documentation, and industry trade-show presence — the company has announced an exhibit at IMTS 2026 (booth #237600).
Mechanical and hardware engineering teams — design engineers, simulation engineers, engineering managers and directors — at organizations in automotive, aerospace, manufacturing and energy, including customers with strict IP-protection and security requirements.
Geography
Headquartered in San Francisco, California, United States. Third-party profile data indicates plans to expand into European and Asian markets by the end of 2027.
History
Founded in 2025 in San Francisco. Cosmon is part of the South Park Commons company portfolio. Its blog records product and company milestones through 2026, including a SOC 2 compliance announcement in April 2026, and third-party trackers record a Series A financing announced in May 2026 following earlier seed participation by South Park Commons and Bison Ventures.
